Unique Design

Tubular membrane for max surface area with incorporated air bladder, stand and interlocking pegs

Easy to Use

screw-on cap and pipette provides easy and safe sample loading and in-process testing with no dangerous needles

Total Sample Recovery

Syringe aspiration of clamp sealed membrane for 90-98% sample recovery

Broad MWCO Range

7 MWCO’s from 0.1 - 100 kD for molecular selectivity from small peptides to large nanoparticles

High Purity

Achieve 98% sample purity with Biotech CE membrane, no heavy metals and sulfides

Featured Application

Drug Dissolution: Controlled release for dose determination

USP Apparatus 2 and 4 compatible

Designed for ultimate convenience, the Micro Float-A-Lyzer® significantly improves handling and dialysis of microliter volume samples. This ready-to-use dialysis device is constructed with high purity Biotech Grade Cellulose Ester (CE) membrane in 7 concise MWCOs from 0.1-100 kD for better molecular selectivity. The Luer® port and included syringe allow for easy loading, in-process testing and sample retrieval without risking needle punctures.

Biotech CE exhibits a fair chemical compatibility and tolerates pH 2-9 and temp 4-37 °C. Exposure to most organic solvents is not recommended and should be confirmed on the Repligen Chemical Compatibility table.
